Question

我正在使用以下代码。

OpenCart 2

我得到的输出如下

<?
echo nl2br( 'The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between 
Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.' , false  ) ;
?>

我想在没有The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between <br> Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.的情况下获得输出，但此时我需要一个换行符（换行符）。

Answer 1

为什么你不能这样做..

<?
echo "The situation deteriorated into attacks on New York elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between\n Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.";
?>

Answer 2

试试这个。顺便说一下，我不知道＆＃34; false＆＃34;是什么？在字符串后面，但如果你在你的代码中删除它，它工作得很好，我看到没有html断行标记。

<?php 
$string = 'The situation deteriorated into attacks on New York elite,followed by attacks on black New Yorkers and their property after fierce competition for a decade between Irish immigrants and black people for work. Rioters burned the Colored Orphan Asylum to the ground.';
function nl2br2($string) { 
$string = str_replace(array("\r\n", "\r", "\n"), "<br />", $string); 
return $string; 
} 
echo"$string";
?>

在PHP中使用nl2br（）
